sulfur
An element that is part of the amino acids cystine and methionine and is therefore present in all proteins. It is also part of the molecules of vitamin B1 and biotin and occurs in foods and in the body as sulphates. Apart from these amino acids and vitamins, there appears to be no requirement for sulphur in any other form and no deficiency has ever been observed, although it is essential for plants.
Not only was the old-fashioned remedy of sulphur and molasses (brimstone and treacle) quite unnecessary, but elemental sulphur is not used by the body.
